Don't try it without Game Shark because the first level just drives you nuts.
There is no starting demo. You see start screen with Last Action Hero logo and quite a catchy tune but that's all.
It is a 2D platformer. The level is well designed and looks interesting. You have to run forward, catch all those floating papers that probably represent the Magic Ticket from the movie. When you have collected the given number of those papers you get the item that let you pass forward. The fire extinguisher for example.
When you meet the first enemy you see that the main reason why this game is so low rated. Fighting action is terribly painful in this game. Because any armed bad guy is tougher, quicker and more armed than you. All you have are your fists and legs in whole the game. OK you get some weapons later but not for man to man fighting actions. You start with bare hands and have to run to the end with these. Missing weapon wouldn't be a big deal if you'd be tough fighter but you are not. Your character is slow and weak and the first enemy teaches you backward long jump that you see painfully lot in this level.
The other moodkiller is time limit. All levels have countdown timer. It wouldn't be a problem if fightings would be normal but no, bad guys are time eaters. First level also needs lot's of annoying jumping actions. Even if you manage to kill all bad guys you probably fall down and run out of time before the end of the level.
The level demands continuous training. And soon you discover that this at first catchy melancholic 15 second sound loop turns to earkiller because you have to listen it over and over. Music tracks of the other levels are different but same type.
But the sound effects are a lot worse or incomplete. There are several sounds: beeping sound if you grab floating sheet of paper, susurrus sound of fire extinguisher and gunshots of enemies. But that's all. Every other actions are silent: your jumping, falling, getting shot and collapsing to death. Even loosing the game is without any sound effect at all.
There is no saving function or even password function. If you die you have some continues and then you have to start over from the first level.
For conclusion. This game would be fun to play if the enemies on the first level would be easier to beat. Their toughness combined with time limit kills whole the fun. Also the copter attack on the third level is too much because you have to avoid bombs and holes, collect tickets at the same time and also must be prepared to the jumping knoll that always appears too suddenly.
With Game Shark timer code the game is quite a fun. The overall graphics are good. There are variety in levels and gameplay. Game even tries to follow the movie script sometimes. Game music is not bad but all the loops are too short. Sound effects are very lame but at least not disturbing. Game intro and ending is not even bad because there is not any intro or demo and also no ending.
The only downside of the gameplay is a pseudo hardness caused by too short time limit. So don't try it without Game Shark because the first level just drives you nuts.
